Scotch® Fire-Retardant and Electric Arc Proofing Tape 77 Series

Scotch® Fire-Retardant and Electric Arc Proofing Tape 77 Series black and size is 50.8mm*6m*0.76mm.

 Scotch® Fire-Retardant Electric Arc Proofing Tape 77 Series are designed to protect most types of electrical cables from fault arc-generated heat and flames of nearby cable failures. These elastomeric tapes are formulated to generate a thick, insulating charred buildup when exposed to high temperatures. The insulating charred buildup protects wrapped cables and cable accessories from the fault arc-generated heat and flames of cable failures within approximately 20 inches until limiting devices can interrupt the faulted circuit. Because Scotch® Fire-Retardant Electric Arc Proofing Tape 77 Series are elastomeric and unsupported, they are very conformable. Installers can provide virtually wrinklefree coverage of cables and irregularly-shaped cable accessories, easily and rapidly. This exceptional conformability provides better product control while wrapping and yields more uniform coverage. Also, the tape’s thin cross section reduces the overall weight compared to other methods while providing arc protection. The white gray color of Scotch® Tape 77 White allows for easy identification of burned areas. One half-lap wrap provides adequate protection for most installations. However, additional wraps can be applied, if conditions warrant, without requiring a reduction in conductor loads.
